离散小波变换在卫星姿控系统故障诊断中的应用

Application of dispersing wavelet transform to fault diagnosis of the attitude control subsystem of the satellite

根据小波分析多分辨分析的特点,讨论利用离散小波变换的卫星姿控系统故障诊断方法,该方法在线实时性好,不需要数学模型,仿真实验收到了满意的结果。

Bused on the feature of multi-resolution of wavelet analysis,this paper uses dispersing wavelet transform to process the fault diagnosis of the attitude control subsystem of the satellite.This method does well in real-time fault and does not need mathematical model of control system.The experiment of simulation is content diagnosis.
